Which command is used to request the network address from a DHCP server?

The command used to request the network address from a DHCP server is DHCPREQUEST. This command is part of the DHCP (Dynamic Host Configuration Protocol) process which enables a client device to obtain IP configuration settings from a server automatically.

During the DHCP process, the client first sends a DHCPDISCOVER message to locate available DHCP servers on the network. Once the client receives offers from the servers (in the form of DHCP Offer messages), it chooses one and responds with a DHCPREQUEST message. This message specifically indicates the server that the client is accepting an offer from and also formally requests the IP address assignment.

The importance of the DHCPREQUEST command lies in its role in completing the process of IP address allocation, allowing the client to finalize its configuration with the selected server. The other options do not pertain to the specific action of requesting an IP address from a DHCP server. For instance, ARP (Address Resolution Protocol) is used for mapping IP addresses to MAC addresses, and netstat is a utility for network statistics, neither of which are involved in DHCP communication.
